Special: Sputnik V hits production roadblock for second dose of Covid vaccine

Russia’s Sputnik V has reportedly hit a roadblock in the advancement of the 2nd dose of its Covid-19 vaccine in India. Resources in the govt have mentioned that the Russian vaccine maker is struggling with producing challenges with manufacturing the second part (Advert5) of the adenovirus vector-based mostly vaccine.

Government sources reported a staff of Russian experts frequented India for around a month to try and iron out the specialized challenges remaining faced by domestic suppliers in developing Advertisement5. Sources reported the 2nd ingredient of the vaccine is more durable to manufacture due to the fact of its design and style as an adenovirus vector-based mostly vaccine.

As opposed to other vaccines which use the same composition of doses for the initial and the second shot, Sputnik V works by using two diverse parts in its Covid vaccine – two varieties of adenovirus vectors (rAd26) for the initial shot and (rAd5) for the 2nd vaccination.

Producing Advert5 is time consuming as nicely, since the produce — or quality of virus that can be developed in a mobile culture — of the second dose (Advertisement5) is very low. If the produce is low, the amount of doses made is low.

The Russian Direct Expense Fund (RDIF), nevertheless, instructed India Now that reports about delays in production of the second element of Sputnik V in India based mostly on anonymous resources are incorrect. “A amount of RDIF companions in India have now manufactured the second ingredient batches, which are undergoing verification at the Gamaleya Middle in Russia. Transfer of technologies to companions in India is also in procedure and there is an lively exchange among Russian and Indian vaccine output experts. RDIF options to accelerate deliveries of Sputnik V and Sputnik Light to India now in August.”

“Output in India is expected to appear fully onstream in September and RDIF expects India to turn out to be a significant production hub for the Sputnik V vaccine with this sort of organizations as Serum Institute of India, the world’s largest vaccine producer, Gland Pharma, Hetero Biopharma, Panacea Biotec, Stelis Biopharma, Virchow Biotech and Morepen Laboratories operating to make the vaccine,” the RDIF told India Now.


The problems in production have impacted the availability of doses for the vaccination concentrate on established by the Indian government to vaccinate all over 18 several years by December 2021. In a Supreme Courtroom affidavit on vaccine doses filed by the central government, the projected believed doses predicted from Sputnik V was pegged at 10 crore amongst August and December 2021.

This projection was reduced by the authorities from an previously estimation of 15.6 crore doses of Sputnik V vaccine for August-December 2021. The projected estimation was for 216 crore doses till December, but In a July 2 press convention, VK Paul, Niti Aayog member (overall health), mentioned “The government’s roadmap of 216 crore doses is an optimistic a single, which was created by banking on the “reputation” of the vaccine suppliers, and ought to be noticed in a dynamic context.”

We have partnered with big hospitals around the state, and set up our cold chain infrastructure throughout 300+ destinations considering the fact that the vaccine calls for -18 degree C temperature.

In India, Dr Reddy’s submitted a proposal to the drug regulator on June 30 for an emergency use authorisation (current market authorisation) and a Phase 3 medical trial protocol for Sputnik Light—a one dose of the vaccine.

But even the solitary-dose proposal has hit a regulatory wall. India’s SEC panel less than the drug regulator denied permission to Dr Reddy’s for an EUA. The minutes of the meeting, which India These days has found, said – “After in depth deliberation the committee proposed that the business should really current the safety, immunogenicity, efficacy data from the section 3 clinical trials of the Sputnik Mild vaccine that is staying carried out in Russia for taking into consideration the proposal.

Further, as the safety and immunogenicity details of ingredient a person has by now been generated in the place in an additional demo, there looks to be insufficient knowledge and justification in conducting a individual very similar trial.”


The Russian vaccine was meant to commence producing a important quantity of doses in July. The timeline has now been pushed to August. In India, the RDIF has production agreements with the Serum Institute of India, Gland Pharma, Hetero Group of Corporations, Panacea Biotec, Stelis Biopharma, Virchow Biotech, and Morepen.
